SUPERNOVA 2008C IN UGC 3611
     K. Ayani, Bisei Astronomical Observatory (BAO); and H. Yamaoka, Kyushu
University, report that a low-resolution (R about 1200 at H_alpha) spectrum
(range 400-750 nm) of 2008C (cf. CBET 1195), taken on Jan. 4.8 UT with the
BAO 1.01-m telescope, shows wide absorption features of Si II and Fe II,
which is typical for type-Ia supernovae near maximum light.  Assuming the
recession velocity of UGC 3611 to be 4983 km/s (Pantoja et al. 1997, A.J.
133, 905), the expansion velocity (derived from the absorption minimum of
Si II 635.5-nm) is 10300 km/s.
